Lidarr uses .NET Core and a new webserver. In order for SignalR to work, the UI buttons to work, database changes to take, and other items. It requires the following addition to the location block for Lidarr:
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $http_connection;
Make sure you
do not include
proxy_set_header Connection "Upgrade"; as suggested by the nginx documentation.
THIS WILL NOT WORK
If you are using a CDN like Cloudflare ensure websockets are enabled to allow websocket connections.
This will not install the bits from that branch immediately, it will happen during the next update.

Error parsing column 45 (Language=31 - Int64)or other similar database errors around missing columns or tables.
This means your SQLite database that stores most of the information for Lidarr is corrupt.
Try the sqlite3
If your sqlite does not have
.recover or you wish a more GUI friendly way then follow our instructions on this wiki.
This error may show if the database file is not writable by the user/group Lidarr is running as.
Another possible cause of you getting an error with your Database is that you're placing your database on a network drive (nfs or smb or something else not local).SQLite is designed for situations where the data and application coexist on the same machine. Thus your *Arr AppData Folder (/config mount for docker) MUST be on local storage. SQLite and network drives not play nice together and will cause a malformed database eventually.
If you're trying to restore your database you can check out our Backup/Restore guide here.
If you are using mergerFS you need to remove
direct_io as SQLite uses mmap which isn’t supported by
direct_io as explained in the mergerFS docs here
Most likely this is due to a MacOS bug which caused one of the databases to be corrupted.
See the above database is malformed entry.
Raspbian has a version of libseccomp2 that is too old to support running a docker container based on Ubuntu 20.04, which both hotio and LinuxServer use as their base. You either need to use
--privileged, update libseccomp2 from Ubuntu or get a better OS (We recommend Ubuntu 20.04 arm64)
Managed to fix the issue by installing the backport from debian repo. Generally not recommended to use backport in blanket upgrade mode. Installation of a single package may be ok but may also cause issues. So got to understand what you are doing.
Steps to fix:
First ensure you are running Raspbian buster e.g using
Distributor ID: Raspbian
Description: Raspbian GNU/Linux 10 (buster)
If you are using buster:
echo "deb <http://deb.debian.org/debian> buster-backports main" | sudo tee /etc/apt/sources.list.d/buster-backports.list
sudo apt update && sudo apt-get -t buster-backports install libseccomp2
Lists never were nor are intended to be
add it now they are
hey I want this, add it eventually tools.
You can trigger a list refresh manually, script it and trigger it via the API, or add the releases directly to Lidarr.
This change was due to not have our server get killed by people updating lists every 10 minutes.
No, nor should you through any SQL hackery. The refresh releases task queries the upstream Servarr proxy and checks to see if the metadata for each release (ids, cast, summary, rating, translations, alt titles, etc.) has updated compared to what is currently in Lidarr. If necessary, it will then update the applicable releases.
A common complaint is the Refresh task causes heavy I/O usage. One setting that can cause issues is "Rescan Artist Folder after Refresh". If your disk I/O usage spikes during a Refresh then you may want to change the Rescan setting to
Manual. Do not change this to
Never unless all changes to your library (new releases, upgrades, deletions etc) are done through Lidarr. If you delete release files manually or a third party program, do not set this to

Unless you're in a repressive country like China, Australia or South Africa, your torrent client is typically the only thing that needs to be behind a VPN. Because the VPN endpoint is shared by many users, you can and will experience rate limiting, DDOS protection, and ip bans from various services each software uses.
In other words, putting the *Arrs (Lidarr, Radarr, Readarr, and Sonarr) behind a VPN can and will make the applications unusable in some cases due to the services not being accessible. To be clear it is not a matter if VPNs will cause issues with the *Arrs, but when: image providers will block you and cloudflare is in front of most of arr servers (updates, metadata, etc.) and liable to block you too
In addition, some private trackers ban for browsing from a VPN, which is how Jackett works. In some cases (i.e. certain UK ISPs) it may be needed to use a VPN for public trackers, in which case you should then be putting only Jackett behind the VPN. However, you should not do that if you have private trackers without checking their rules first. Many private trackers will ban you for using or accessing them (i.e. using Jackett) via a VPN.
/all endpoint is convenient, but that is its only benefit. Everything else is potential problems, so adding each tracker individually is strongly recommended. Alternatively, you may wish to check out the Jackett & NZBHydra2 alternative Prowlarr
May 2021 Update: It is likely *Arr support will be phased out for the jackett
/all endpoint in the future due to the fact it only causes issues.
/all endpoint has no advantages (besides reduced management overhead), only disadvantages:
Note that using NZBHydra2 as a single aggregate entry has the same issues as Jackett's
Add each indexer separately. This allows for fine tuning of categories on a per indexer basis, which can be a problem with the
/all end point if using the wrong category causes errors on some trackers. In *Arr, each indexer is limited to 1000 results if pagination is supported or 100 if not, which means as you add more and more trackers to Jackett, you're more and more likely to clip results. Finally, if one of the trackers in
/all returns an error, *Arr will disable it and now you do not get any results.
This is expected. Below is how the Torrent Process works.
Hardlinks are enabled by default. A hardlink will allow not use any additional disk space. The file system and mounts must be the same for your completed download directory and your media library. If the hardlink creation fails or your setup does not support hardlinks then will fall back and copy the file.
Lidarr is not like the other Arrs. It uses tags instead of file names for operation. If you keep Lidarr files on cloud storage, it has to download the file to read the tags. This will very quickly blow through any API limits you have on your storage provider. We very much discourage you from keeping your Lidarr library on a cloud storage provider, and any issues you may be experiencing are likely due to that setup.
